Fix typos and grammatical errors across Unity Editor UI and documentation strings

[davilkus-dev]

Summary

This PR fixes various spelling mistakes, typos, and grammatical inconsistencies discovered in the Unity Editor-side scripts. These changes improve the overall professionalism and clarity of the plugin for developers using the CAS.AI SDK.

Key Changes

1. General Spelling & Typos

• Fixed "Mediaiton" to "Mediation" in several UI labels.
• Fixed "performanc" to "performance" in developer-facing warning boxes.
• Fixed "sdk" to "SDK" for consistency in labels.
• Corrected "Mininum" to "Minimum".
• Fixed "propery" to "property" in tooltips.

2. Grammar & Phrasing

• "A" vs "An": Corrected several instances where "an" was incorrectly used before "CAS" or "manager" (e.g., changed "an CAS account" to "a CAS account").
• Verb Tense: Corrected phrases like "The CAS begin" to "CAS begins" and "CAS required" to "CAS requires."
• Clarity: Improved the phrasing of error dialogs to make them easier to understand (e.g., changing "in the first place CAS Settings Window else contact support" to a more natural structure).

3. File Naming

• Identified a typo in the filename CASInitSettignsInspector.cs (should be CASInitSettingsInspector.cs).

Specific Lines Replaced

• BaseAdObjectInspector.cs: Fixed grammar regarding initialization and ConsentFlow selection.
• BannerAdObject.cs: Fixed "a AdView" to "an AdView."
• CASEditorSettings.cs: Fixed "propery" typo.
• CASInitSettingsInspector.cs: Extensive cleanup of the HelpBox descriptions, including fixing "performanc," "sdk," and the Rewarded ad logic explanation.
• CASPreprocessBuild.cs: Fixed build-time warning messages and platform requirement strings.
• ManagerIndexDrawer.cs: Fixed the "Mediaiton" spelling error in the inspector.

Impact

• No functional changes to ad delivery or logic.
• Improved user experience (UX) for developers using the Unity Inspector and build tools.
